What PESA radar? Fire Control for SAMs is done through the MR-90 Orekh which is a pulse doppler slotted array type.
Again, what PESA? The only phased array radar of any kind on Talwars is the 5P-10 Puma which does fire control for the 100mm gun, not for any missiles.
The Fregat-M2EM is PESA. So are the Orekhs.
Even the fire control for most of their land based Buk is PESA. It's the Chinese who are stuck with cassegrain antennas.
Look at the Fregat specs.
It speaks of "pencil beams", which is only possible with phased array radars, PESA and AESA. Since it speaks of wave travelling tubes, it's PESA. I mean, just looking at the radar can tell you it's a phased array.
The Russians switched to PESAs since the 80s and 90s for pretty much everything. It's only the old ships which still have older types of antennas, like cassegrain.
Even if the Orekh is not PESA, it's still fine since it's a single role radar.
You sure they're not counting usage against surface targets? They've considered that in the past, where 32km SAM is up to ~50km against surface targets.
You are talking about the effectiveness of the radar up to horizon. This is due to the limitations of physics due to radar horizon, it doesn't speak for the effectiveness of the radar itself. With more range, it's obvious even the FCR will get the necessary upgrades.
The reason why a dedicated FCR is used is because the main array is not always facing the target since it rotates. If it wasn't for that, we wouldn't need the Orekhs.
Any advantage in low observability brought by Talwar compared to Delhi is meh. Even P-15A and P-17 are meh. None of these ships are a problem to acquire with modern sensors at any useful range. If we came up with a ship with a hull like Zumwalt or Visby, then that is something.
Acquisition is easy, but early detection is not. The IOR is peppered with ships.
High end compared to what? Ships from 30 years ago? By mid-2020s, even PN will be sailing FFGs with AESA as their frontline warships. So the Talwars won't compare favourably even with the modified Type-054As (fitted with AESA) that PN is going to get.
Chinese Type 054 and 54A are pretty much the same as the Talwar. And they will stay that way for a very long time. The Pakistanis are basically getting a less capable Talwar class. The only way it can match the Talwar is if they manage to equip it with the HQ-16C and Brahmos.
Basically, the best Type 054A today is relatively inferior to the newest Talwar class in terms of weapons employed.
Compared with IN's frontline, these ships have a highly inferior sensor suite, a CMS that will be incompatible to function as a piece of the CEC puzzle in future, and another quip I have with this deal is that we continue to give business to Zorya-Mashproekt even after they screwed us in the P-15B project with their delivery delays on the turbines.
The Talwars are also frontline ships. Their sensor suite is no doubt inferior to the MFSTAR, but it's fine, it works exactly as we want it to.
The engine delay was fine. The Russian produced shaft lines were delayed, so when the shaft line delivery was expected to be delayed, the Ukranians modernised the engine even further, which will finish only this year. Plus, there's been a delay with the supply of the MFSTAR also. What's important to consider is sometimes these "delays" are not deliberate but done in order to modernise much more than planned. The same thing happened with Vikramaditya. Since it was delayed anyway, a lot of stuff that was supposed to be added during the first refit was instead done before delivery, which further delayed delivery.
If Scorpene was delayed a bit more, we would have taken 2 more years to add an AIP plug to it instead of doing the same during refits at a later date.
CEC on the P-15As is ready and working.
I know. But we still need to integrate aircraft with it. The P-15A do not exactly have CEC to the fullest extent. As I've pointed out, CEC is about integrating two or more independent systems together. Like the Ka-31 with the Kolkata class. The Barak was always designed to integrate with other SAMs anyway. In our case, it will be easily integrated with the Akash, SPYDER, QRSAM, BMD etc.
You can go the most secure high bandwidth datalink, but you can't get a Talwar to fire Barak-8s off a Kolkata-class. For the same reason why you can't get ELM-2084 (or ground based ELM-2248) to substitute their Russian equivalents in IAF's S-400 batteries. I already painted the picture, it isn't just a question of sharing information, its about compatibility as well.
The S-400s will be integrated with the LRTR. So both EL/M 2084 and the S-400's Gravestone can receive early warning from the LRTR through the IACCS. Whether the S-400 will be able to fire off Baraks or not, that will depend entirely on how well we integrate the Barak missiles with the IACCS, which we can easily do. Whether we can use the Barak to fire S-400 missiles, that depends on how well we are able to integrate the S-400 missiles with the IACCS. The Israelis and Russians only have to modify the missiles to our specs, so that the missiles can speak to both the Gravestone and the EL/M 2084 and their respective CPs using a common datalink.
Vikrant can take control of all SAMs on any P-15A/B or P-17A in the vicinity. Talwars will remain outcast.
By the time the Vikrant is fully kitted out, they say 2023, it will be able to do that with the Talwar also.
